The objective is to demonstrate character/ symbol frequency distribution analysis (reference to the English language) on 2 vintage ciphers, namely Caesar cipher (a mono-alphabetic substitution cipher) and the Vigenere cipher (a poly-alphabetic substitution cipher).

matlab中tic与toc函数联合进度条使用例子(tic toc function matlab in combination with the use of examples progress bar)

用matlab编写波前编码系统光学传递函数mtf在不同离焦下随相位板参数的变化曲线(the curve of mtf along with the change of phase plate parameters under different focal )

目前心率变异性分析已成为当今生物医学工程研究的一个热点，再次我把我分享的心电信号的HRV分析工具上传，更好的服务正在研究这个方向的同行。(heart rate variability analysis tools)

说明：  计算弯曲线天线的输入阻抗，辐射方向图以及增益（可以计算不同的直线长度，弯折次数，弯折高度，弯折角度的弯曲线天线）(Calculation of bending wire antenna input impedance, radiation pattern and gain (the straight line can be calculated in different length, bending frequency, a high degree of bending, bending angle of bending wire antenna))
